Hematopoietic stem cells (HSCs) are regulated by multiple components of the hematopoietic niche, including bone marrow-derived macrophages and osteomacs. However, both macrophages and osteomacs are phenotypically similar. Thus, specific phenotypic markers are required to differentially identify the effects of osteomacs and bone marrow macrophages on different physiological processes, including hematopoiesis and bone remodeling. Here, we describe a protocol for isolation of murine bone marrow-derived macrophages and osteomacs from neonatal and adult mice and subsequent identification by multi-parametric flow cytometry using an 8-color antibody panel.
